Most users are successfully utilizing the 1MB FXVL_125C_V binary (often sourced from verified community repositories like BillyCurtis on GitHub) paired with the nvmupdatew64e (Windows) or nvmupdate64e (Linux) utility found in the latest Intel Ethernet Adapter Complete Driver Pack (v30.6 or higher). To apply the fix, you must place the binary and utility in the same folder, configure the nvmupdate.cfg file to target the i226-V (Device ID 125C), and run the update command—.\nvmupdatew64e.exe -u -l -b -c nvmupdate.cfg for carecredit dental Windows or sudo ./nvmupdate64e -u -l -b -c nvmupdate.cfg for Linux—followed by a mandatory cold boot (unplugging the power for 30 seconds) to ensure the hardware properly initializes the new firmware.
